C#编程，从键盘输入一个数组

Question

C#编程，从键盘输入一个数组从键盘输入一个数组，要求打印出这个数组中所有数的平均值以及数组中所有比这个平均值大的数

Answer 1

1. 键盘输入12,23,34,45，即字符串以逗号分隔，用split方法拆分为数据，帮助中有例子，简单修改即可。

2. 建立数组，如只有26个字母，则维数26，循环字符串，用switch判断第几个字母，并在对应的数据中加1，显示时，为0的数组数据不显示，显示的第几维，则字母就是第几个。

3. 如果是中文判断，要使用动态数据arraylist。

C#数组有4种写法

1. ArrI=new Array();

   ArrI[0] = new Array("username1","0","609");

   ArrI[1] = new Array("username2","609","610");

   ArrI[2] = new Array("username3","609","611");

2. ArrII=new Array();

   new Array("username1","0","609"),

   new Array("username2","609","610"),

   new Array("username3","609","611")

3. ArrIII=[];

   ArrIII[0] = new Array("username1","0","609");

   ArrIII[1] = new Array("username2","609","610");

   ArrIII[2] = new Array("username3","609","611");

4. ArrIIII=[];

   ["username1","0","609"],

   ["username2","609","610"],

   ["username3","609","611"]
